Wiring mains to the MLSJC6PSU
The entry for the mains wiring can be made by drilling a conduit of around 20mm at the bottom or
either side of the enclosure. These wires are to be terminated at the MCB and Mains terminal
blocks on the right side of the MLSJC6PSU. The MCB and the terminal blocks are prewired to the
MLSJC6PSU in the factory as shown in Fig. 2 below.
